WIRE-TWISTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 369,765, datedSeptember 13, 1887.

Application tiled April 13, 1887. Scl-inl No. 234,589. (No modeLl To allwhom, it may concern,.-

Be it known that I,W1LL1AM M. AUGUsrINE, a citizen of the United States,residing at South Bend, in the county of St. Joseph and State ofIndiana, have invented certain new and useful Improvements inWire-Twisting Machines for Constructing Combined Wire and Iicket Fences;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in machines for twisting thelongitudinal supporting-wires around the pickets of a combined wire andpicket fence; and it consists in eertain novelty in the construction andarrange-v ment of the various parts of the same, all of which I will nowproceed to point out and describe, reference being had to theaccompanying drawings, in which- Figure l is a perspective of my saidinvention, showing the same in use, a section of fence being shown inprocess of construction.

Fig. 2 is a vertical central section of the same, A

and Figs. 3 and 4 are details showing various parts of my invention.

Referring to the drawings, A represents a suitable standard or boardforming the frame of the machine, on which the twisting mechanism ismounted. Said standard is provided on its rear side with a handle, A',for moving the same.

ct are a series of apertures in the center of said standard, arranged ina vertical line one above the other.

B B are similarly-formed reciprocating rackbars mounted in suitableguides, a, on the front of the standard and located on either side oftheapertures a.

C is an operating-lever pivoted at its center on a bolt, c, secured inthe upper end of the standard, said bolt forming the fulcrum ofthelever. The lever C is connected with the rackbars by arms c c', theupper ends of said arms being pivoted to the lever and their lower endsto the upper ends of the rack-bars. By means of this lever the rack-barsare reciprocated, for a purpose hereinafter set forth.

a2 a2 are two series of holes arrangedon each side of the standard Aimmediately above the rack-bars and in a vertical line with saidrack-bars. Said holes are provided with adjustable stop-pins c a3, whichengage with the upper ends of the rack-bars and limittbe movement ofthesame.

D are suitable twister heads, preferably conical in form, as shown, andhaving formed on their smaller ends and integral therewith pinions D andextensions D2, of less diameter than the pinions. Between the conicalportion of eachtwister-head and its pinion is formed an annular groove,d. The pinions D of the twister-heads are mounted between and engagewith the rack-bars B B, and the eX- tensions D'z extend through theapertures a, but do not have a bearing in said apertures. Saidtwisterheads are held in position by flanges b b on either side ot' therack-bars, which flanges engage with the grooves d, and the sides of thepinions approximate to the standard. In each twister-head are suitablewire receiving apertures, E E, having openings e e in the larger end ofthe twister-head, arranged diametrically opposite each other. Saidapertures E E converge to a common aperture, E, which extends throughthe pinion and extension and has an opening, e', in said extension.

Any desired number of twister-heads may be used, according to the heightof the fence to be constructed and the distance apart it is desired toplace the longitudinal supportingwires.

In Fig. l, F represents a section of fence in process of construction. Fare the pickets, and f the pairs of longitudinal supportingwires.

In operation each pair of longitudinal wires are first threaded throughthe apertures in thetwister-heads. Thewiresarethenstretched from end toend and secured to posts or to any other suitable device for holding thesame. The machine being in the position shown in Fig. I, a picket isinserted between each pair ot' wires. Then by operating the lever therack-bars arereciprocated, one going up while the other goes down, thusturning the twisterheads and twisting the wires. Taking hold of thehandle A', the machine is moved a suitable distance, another picket isinserted, and the operation repeated, and so on until the section offence is completed. As each section is completed, the wires are securedto suitable posts. When the ends of the wires have been reached, theyare released from the post or other device from which they werestretched and the machine removed from said wires.

By means of the stop-pins a3 as the amount of twist given the wires maybe regulated, said pi-ns being adjusted to limit the move ment of therack-bars so as to turn the twister half around, once around, once and ahalf or twice around, and thus twist the wires as much as desired.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl. In the herein-described wire-twistingmachine, a standard provided with apertures arranged one above the otherin a vertical line, two reciprocating rack-bars mounted on the standardon either side of the apertures, and an operating-lever connected withthe rackbars, in combination with suitable twisterheads extendingthrough the apertn res in the standard and having pinions mountedbetween and engaging With the rack-bars, and provided withwire-receiving apertures having openings diametrically opposite eachother in one end of the twister-heads and converging to a commonaperture having an opening in the opposite ends of saidtwister-heads,all constructed, arranged, and operating substantially asset fvorth. 1

2. In the herein described Wire twisting machine, a standard providedWith apertures arranged one above the other in a vertical line, tworeciprocating rack-bars mounted on the standard on either side of theapertures and provided with projecting flanges on either side of theracks, an operating lever connected with said rack-bars, and adjustablestop-pins on said standard for limiting the movement of said rack-bars,in combination with suitable twister-heads extending through theapertures in the standard and provided With pinions mounted between andengaging with the rackbars and held in place by the iianges of saidrack-bars, said pinions being provided with Wire-receiving apertureshaving openings diametrioally opposite each other in one end of thetwister-heads and converging to a common aperture having an opening inthe opposite end of said twister-heads, all constructed, arranged, andoperating substantially as shown and described.

3. In a Wire-twisting machine, the standard A, having the apertures a,arranged one above the other in a vertical line, the reciprocatingrackbars B B, suitably mounted on the standard on each side of theapertures a, and the operating-lever C, connected with the rackbars B B,in combination with the twisterheads D, having the pinions D mountedbetween and engaging with the rack-bars, and the extensions D2,extending through the apertures a, said twister-heads being providedwith wire-receiving apertures E. E, having openings e e in one end ofthe twister-heads and converging toacommon aperture, E', having anopening, e', in the end of the extension D2, all constructed, arranged,and operating substantially as shown and described.

4. In aWire-twisting machine, the standard A, provided with apertures a,arranged one above the other in a vertical line, the reciprocatingrack-barsB B, suitably mounted on the standard and having projectinganges b b, t'he operating lever G, connected with the rackbars, and theadjustable stop-'pins a a3, for limiting the movement of the rack-bars,in combination with thetWister-heads D, having the wirereceivingapertures E E, converging to a common aperture, E, said aperturesextending through the twister-heads and provided with the annulargrooves d, pinions D', and extensions D2, said pinions being mountedbetween and engaging with the raGkbarSand'heId in place by the flangesbb of said rack-bars, and said extensions D? extending through theapertures a in the standard. all constructed, ar-
